Peridot: A stone born from the movement of the earth...

Most gemstones are formed in the earth’s crust but Peridot, the birthstone of August, is one of only two gemstones (the other being the diamond) that is formed deep in the earth’s mantle. This beautiful green stone can be brought to the surface by tectonic movement or volcanic eruption. This is why for three and half thousand years the volcanic island of Zabargad, near Egypt, was the main source of the stone. Cleopatra's famous emerald collection is actually thought now to have been peridot jewellery.

... and descended from the heavens...

Peridot is the only stone known to exist on other planets. Olivine, which is the original form of peridot has been found in several meteorites that have fallen to earth, although the recovered gems are not as large as those found on earth.

In 2003, scientists from NASA discovered 19,000 square miles of the stone on Mars, which is thought to have been pushed to the surface through faults and fractures. The stone has also been found on the moon.

The evening emerald

Peridot is one of the few gemstones that can be found only in one colour, although the shades of green vary across a range of hues that make up these mesmerising shades. Loved by the Egyptians and the Romans who called it "the evening emerald" because its colour didn't darken at night, this luxurious green stone has been a favourite through time and space and enlivens any jewellery.
